GAS-BURNER.

Specification of Letters Patent.

'latcntell June 28, 1921.

Application filed October 11, 1920. Serial No. 416,054.

To ((711074 0m ii in my concern Be it known that we, ELMER 1 tloiuswnu. and JOSEPH H. MoURnAoY, citizens of the United States, and residents of Okmulp ee, in the county of ()kmulgee and State of Oklahoma, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

Our invention relates to improvements in gas burners, and more particularly to one adapted for use in oil fields for firing the boilers with low pressure gas and maintaining proper steam pressure for drill work or the like, considerable difliculty having been heretofore experienced in obtaining the proper burner to consume gas at low pressure as is common in certain sections or oil regions, and particularly the middle and southwestern sections of this country.

It is therefore the purpose of this invention to provide a device of the character named which will operate efficiently and continuously, without clo giug up or failing to operate, and possessin; a number of improvements as will be hereinafter more particularly set forth.

Other and further objects of our invention will become readily apparent to persons skilled in the art, from a consideration of the following description when taken in conjunction with the accompanying drawings, wherein:

Figure l is a plan view burner, and

Fig. 2 is a front elevation thereof partly broken away and in section.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several views, our improved burner is shown as comprising a horizontal supply pipe for low pressure gas or oil, indicated at 10 and leading into a header ll perpendicular thereto, said header being preferably of tubular form, imperforate and closed at the ends 12 thereof.

Leading perpendicularly to the header at the opposite side with respect to the position of location of the supply pipe or lead 10, are a series of header pipes 13. In the preferred construction, these header pipes are arranged in parallel relation and extend perpendicularly to or at right angles from the header 11 in alincment with the supply pipe 10 and at the extremities of of the improved the header ii. the free ends 14 thereof being closed while connnunication is established through the opposite ends thereof with the header in order to permit the proper flow of the gas or oil to the same.

Extending vertically at right angles to the header pipe 13 are a series of perforate tubes or mixing chambers 15, preferably equi-distantly spaced apart and suitably joined to the headers 13 at their lower ends, as more particularly shown in Fig. 2 of the draw ings. These upright tubes or mixing chann bers are provided near their lower ends. preferably at the juncture with the header pipes 13. with air inlet openings 16 leading. directly from the upper face of each header pipe 13 and extended upwardly for some distance to give the proper opening for the entrance of the required volume of air thereto, in order to mix with the gas escaping through the burner orifices or holes 17 lead in e through the confined upper portions of the header plpes 13 into the lower ends of the upright tubes or mixing chambers 15 as shown in both Figs. 1 and 2. The header pipes 13 in practice are preferably about two inches in diameter and the orifices are made of the proper size to allow the required volume of gas to pass through so as to intermix with the air drawn through the openings 16 in the manner of a Bunsen burner. The orifices in the outer header pipes 13 are preferably arranged near the outer portions of the walls thereof within the area of the mixing tubes or chambers, while the orifices of the central header pipes are preferably arranged in staggered or zigzag relation, in order that the gas will be properly supplied to the various upright mixing chambers or tubes, the result being a carbonless blue flame which will produce a maximum heat, without causing the burners to leg up and render the device inope1 ative until cleaned, as has been heretofore experienced with devices for the purposes of this invention. The arrangement is such as to properly adapt the device to various forms of boilers or the like, and particularly those used in oil fields. Furthermore, it IS obvious that while we have described what is now considered the preferred embodiment of the invention, obvious minor changes in the details of construction may be made without departing from the spirit of the invention as hereinafter claimed.

In view oi the foregoing, it is thought that the operation of the deviee Will be readily understood and in view of the siniplieity and prarlirahility thereof, that it will commend itself to those skilled in the art.

Having thus partirularly desrribed and asi-ertained the nature of the invention, and in what manner the same is to he performed, what is Planned is:

l. A burner of the class described romprising a supply pipe, an imperforate straight header r oniniunieating therewith intermediately and having closed ends, a plurality of header pipes extending from said header and having the free ends thereof closed. there being outer pipes and an intermediate pipe disposed in parallel relation with respect thereto, said header pipes being provided with burner orifices in the upper walls thereof located in spared relation and the burner orifices of the central pipe being disposed in zig-Zag relation near the sides thereof, and upwardly extending mixing r'harnbers encompassing said orifices and having the upper ends thereof eompletely open, said mixing chambers having their lower ends bifurcated to provide spared side portions secured to the header pipes and producing air inlet openings alined in the direction of the header pipes.

2. A burner for the purposes specified, comprisinga horizontal supply pipe for oil or low pressure gas, a header arranged perpendieularly thereto and having closed ends, a plurality of header pipes extending perpendieuhirly to the header at the opposite side thereof, one of said header pipes being arranged in alineinent with the supply pipe and the others being arranged adjacent to the ends thereof, said header pipes being disposed in parallel relation and having elosed free ends, a plurality of equi-distantly spared upright burner tubes arranged upon the header pipes and substantially lone-- sponding in diameter thereto, said tubes having air inlet openings near their lower ends and leading to their juncture with the header pipes, said header pipes having burner orili es in their upper portions confined by said tubes.

3. A burner for the purposes specified, eoinprising a horizontal supply pipe for oil or low pressure g: s, a header arranged perpeudieularlv thereto and having closed ends. a plurality of header pipes extending per pendieularly to the header at the opposite side thereof, one of said header pipes being arranged in alineinent with the supply pipe and the others being arranged adjat-ent to the ends thereof. said header pipes being disposed in parallel relation and having i-losed free ends. a plurality of equi-distantly s 'iaeed upright burner tubes arranged upon the header pipes and substantially Corresponding in diameter thereto, said tubes havingr air inlet openings near their lower ends and leading to their juncture With the header pipes, said header pipes having burner orifires in their upper portions confined by said tubes, the upper ends of the tubes being open, the orifices of the outer header pipe being, lot'ated in alineinent near the outer Walls thereof and the orifires of the intermediate header pipe disposed in alinement with the supply pipe being located in stag gored relation.
